Some of the hypocrites made excuses of the warmth of the weather, and with the aim of scattering Muslims, did not attend the noon congregational prayer, which was always performed by the prophet collectively. Some of the new converts too, followed the hypocrites and absented themselves from the prayer! The prophet was worried about that, and in order to overcome and obliterate the tricks of the hypocrites, he insisted in performing the noon prayer, even so; congregationally. This, of course, was difficult for the followers to follow it, in that hot weather of Arabian summer. The verse then appeared and put an stress and emphasis upon the matter.
